Extended coupled-pair many-electron

J. Paldus, J. Cizek, and 1. Shavitt, Correlation problems in atomic and molecular systems. IV. Extended coupled-pair many-electron theory and its application to the BHs molecule. Phys. Rev. A 5, 50 (1972). [Pg.382]

The success of this rather abrupt truncation for closed-shell molecular systems is not too surprising when one considers that the dominant terms of a perturbation expansion have been included.2 616 The next more complete approximation to attain recognition is the extended coupled-pair many-electron theory (ECPMET) of Paldus, Cizek, and Shavitt,6,17,18 which includes connected single and triple excitations,... [Pg.210]
